Hi Experts,

DATA: client TYPE REF TO if_http_client.

CALL METHOD CL_HTTP_CLIENT=>CREATE_BY_URL

EXPORTING

url = url_string

IMPORTING

CLIENT = client

EXCEPTIONS

ARGUMENT_NOT_FOUND = 1

PLUGIN_NOT_ACTIVE = 2

INTERNAL_ERROR = 3

others = 4.

IF sy-subrc <> 0.

WRITE: / 'Client Object could not be created. SUBRC=', sy-subrc.

EXIT.

ENDIF.

• Set Header Field of request

CALL METHOD client->request->if_http_entity~set_header_field

EXPORTING

name = '~request_enctype'

value = 'multipart/form-data'.

CALL METHOD client->request->if_http_entity~set_header_field

CALL METHOD client->send

EXPORTING

TIMEOUT = CLIENT->CO_TIMEOUT_INFINITE

.

IF sy-subrc <> 0.

WRITE: / 'Request could not be sent - communication error. SUBRC=',

sy-subrc.

EXIT.

ENDIF.

• Receive Response

CALL METHOD client->receive

IF sy-subrc <> 0.

WRITE: 'Response not obtained - communication error SUBRC = ' ,

sy-subrc.

EXIT.

ENDIF.

• Close HTTP connection

CALL METHOD client->close

EXCEPTIONS

OTHERS = 2.

IF sy-subrc <> 0.

WRITE 'HTTP connection in undefined state'.

ENDIF.

*End of code.

The problem here is I am getting exception "http_connection_failed" in recieve method.

Can any body help me out.

Thanks in advance.
